Why should there be Internet neutrality?

Recently Verizon and Google issued a joint statement in which they said that Internet service providers should be allowed to charge a premium for quicker Web access. Like most everyone else, my initial reaction was outrage. Everyone should be allowed to get the same access for their service fee. Or should they? ISPs are businesses, so why shouldn’t they maximize their profits? I tried to find an analogy to counter this, but I can’t find any. There is nothing quite like the Internet. The airwaves are licensed to radio and television stations. Book publishers have complete control over what they publish. Can we compare the Web to telephone service or electric service? Should ISPs be turned into semi-public utilities?
